如何在CLion中解决Boost.Asio出现的undefined reference to `__imp_WSACleanup'错误

Question

我的C++项目包含Boost和WebSocket++库。我阅读了其他主题，需要在gcc命令中添加-lws2_32，但我使用的是CLion，不知道该如何解决。

控制台：

CMakeFiles\WsServer.dir/objects.a(main.cpp.obj): In function `boost::asio::detail::winsock_init_base::startup(boost::asio::detail::winsock_init_base::data&, unsigned char, unsigned char)':
C:/MinGW/include/boost/asio/detail/impl/winsock_init.ipp:39: undefined reference to `__imp_WSAStartup'
CMakeFiles\WsServer.dir/objects.a(main.cpp.obj): In function `boost::asio::detail::winsock_init_base::cleanup(boost::asio::detail::winsock_init_base::data&)':
C:/MinGW/include/boost/asio/detail/impl/winsock_init.ipp:56: undefined reference to `__imp_WSACleanup'
collect2.exe: error: ld returned 1 exit status
mingw32-make.exe[3]: *** [CMakeFiles\WsServer.dir\build.make:99: WsServer.exe] Error 1
mingw32-make.exe[2]: *** [CMakeFiles\Makefile2:67: CMakeFiles/WsServer.dir/all] Error 2
mingw32-make.exe[1]: *** [CMakeFiles\Makefile2:79: CMakeFiles/WsServer.dir/rule] Error 2
mingw32-make.exe: *** [Makefile:117: WsServer] Error 2

我该做什么？

您可以在CMakeLists.txt中通过target_link_libraries传递ws2_32，例如：

if(MINGW)
  target_link_libraries(YourTargetName ws2_32)
endif()
